Merge branch 'icc-imx8mp' into icc-next

This patchset is to support i.MX8MP NoC settings, i.MX8MP NoC initial
value after power up is invalid, need set a valid value after related
power domain up.

This patchset also includes two patch[1,2] during my development to enable
the ICC feature for i.MX8MP.

I not include ddrc DVFS in this patchset, ths patchset is only to
support NoC value mode/priority/ext_control being set to a valid value
that suggested by i.MX Chip Design Team. The value is same as NXP
downstream one inside Arm Trusted Firmware:
